Spaced vertically above these projeeting members are similar iiai'rowprojecting members c, vertically adjustable upon t4 dependingextremities ot' the opposed series of fingers by means of slotted stemsn and studs c?.

These extremities grip orpinch the upper margins of the spring platesIand pattern and exert a pressure thereon eorrespending to that of thelower projections t," upon the lower margins ot' the spring and pattern.

Each upper projecting member upon the stationary series of fingers isprovided with an extended shoulder e whieh extends over thel pattern t)and rests upon the upper edge of the spring plate N. thus preventing theplate from wai-'ping in the direelion ot its plane. y

The spring is thus einbrared upon sides and upper edge, b rigid lingermembers and forced into elose engagement with the depending grating atits lower edge. and in this position while piiiehed into liiial shape bythe pressure bet\veen"the stationary and movable series ot lingers,tht-'tempering tank is elevated until the platform and tingers inelosingthe spring plate and pattern are immersed in the tempering luid, which'sets the spring until it' will retain its litted shape al`tei2it isreleased t'rom the lingers.
